The purpose of this study is to compare the incidence of EA in pediatric patients undergoing minor ENT surgery under Sevoflurane and compare opioid-only based intra-operative analgesia to multi-modal analgesia consisting of opioid and IV acetaminophen or PO acetaminophen regimen using a validated and standardized EA measurement tool, the Pediatric Anesthesia Emergence Delirium (PAED) scale. The post operative pain scores will be measured in all patients by post-op recovery staff using FLACC Score/Wong-Baker FACES (patients 24 months up to 7 years of age) or Numeric Pain Score for patients 7 years of age. The pre-operative, surgery, anesthesia and post-operative staff will be all blinded.
